My silverado might be haunted because the rear planetary piled up. Irebuilt the 4L60E and installed it. Truck won't start. O K, Iprogrammed the PCM and got by security. Truck won't start. When I hook power wire to crank sensor fuel pump starts.Some spook is messing with my wiring. Only wanted to rebuild tranny& now have more work. I even told the wife that the Silverado has a demon fighting against me.
